The real cost of double data entry
Take an ordinary day. An order comes in on WhatsApp. Someone copies it into an Excel spreadsheet, then prepares the invoice in another piece of software. The customer pays with Orange Money: the payment is noted in a notebook or an Excel file. At the end of the month, the accounting team re-enters everything to reconcile the figures.
Each step seems harmless. Put end to end, they are expensive. Ten minutes of re-entry per order, at thirty orders a day, adds up to five hours of work every day spent copying information that already exists. Not to mention the errors: a price copied wrong, a forgotten payment, a customer invoiced twice.
The heaviest cost lies elsewhere, though: information arrives late. The manager discovers a stockout when the customer calls, and the real revenue figure once the accounting close is over.
An API, in plain terms
An API is a service window that one piece of software opens to others. It makes its data available there and accepts the data sent to it, according to precise rules: who is allowed in, what information, in what format.
When two tools communicate through an API, an order placed on the website goes straight into stock management, the mobile money payment attaches itself to the right invoice, and the accounting entry is generated without anyone stepping in. Nobody copies anything anymore: the team checks and decides.
Three ways to connect your tools
There is no single method. The right choice depends on what your software can do.
- Real-time API. Both tools expose an API and data flows within seconds. This is the natural route for an e-commerce site, a payment platform or a mobile app.
- Scheduled file exchange. Your software has no API, but it can export and import files. A program picks up the export every night, checks it and imports it on the other side. Less elegant, but often safer with on-premises accounting software and ERPs, SAGE included.
- Integration platform. Beyond three or four tools, direct connections turn into a plate of spaghetti. A central hub receives, transforms and redistributes the flows, keeping a log of every exchange.
Many companies combine all three. What matters is choosing flow by flow, not once and for all.
The costly pitfalls
Reference data that drifts apart. The same customer exists under three names, the same item under two codes. Connecting these tools without cleaning them up just automates the mess. Before any integration, decide for each piece of data (customer, item, price) which tool is the source of truth. We covered this in Name your tables the way you name your variables.
Network outages. A connection that assumes a permanent link will eventually lose data. A serious integration queues the transmissions and resumes them on its own when the connection comes back.
Duplicates. When a transmission fails and is sent again, the same payment must only be counted once. This has to be planned at the design stage, not after the first customer complaint.
Nobody is watching. A flow that stops silently is worse than manual re-entry. Every exchange must leave a trace, and every failure must trigger an alert.
Wanting everything at once. The big project meant to connect everything in one go gets bogged down. A well-chosen first flow, automated and measured, justifies and funds the next ones.
The principle we apply to our own software
This is not theory. It is the rule behind the software we publish: information is entered once, then it flows.
- VISIO FACTURE chains quotes, pro forma invoices, orders, deliveries, invoices and credit notes without re-entering a single line. Payments by Orange Money, MTN MoMo, bank transfer or cash attach to the invoice, and the balance due is recalculated automatically.
- VISIO PHARMA turns every pharmacy sale into a SYSCOHADA accounting entry. Installed on site, it keeps working without internet and resyncs with the cloud as soon as the connection returns.
- VISIO TRANSIT carries the information entered when a freight file is opened through to customs, invoicing and accounting.
Where to start
- List your tools and the information that moves from one to another.
- Find the most frequent re-entry, or the one where an error costs the most.
- For each piece of data, decide which tool is the source of truth.
- Check what each tool allows: an API, file exports, or nothing at all.
- Automate a first flow, measure the time saved, then expand.
